Tablets might be the direction for Google to release its Android 3.0 oS (Honeycomb). But the best part is that it is not just for tablets. Based on the evidence in the SDK emulator which was previewed, it seems that the guys at Google have something coming up for smartphones.
On the working part, this is how it is done: an arbitrary screen resolution can be set for loading by the emulator.The resolution, by default, is set as WXGA (1280 x 768) which works brilliantly for tablets. But even this can be a bit large for bigger smarthones. The setting can be changed to WVGA (which are found in smartphones ranging from mid-to-high end models). But, this setting somehow activates a different kind of UI and fails to display Google's gizmo-type homescreen stuff, which was shown on the Honeycomb tablets. Well, the default launcher crashes completely and so, it is better to install a home-replacement application (such as LauncherPro which works smoothly).
The home-replacement application helps to get inside and play around with the UI. Once you are in, you will notice that there are traces of smartphone support. In the case of the status bar, it reverts to a smartphone form which has correlation with pre-Gingerbread background and has incorrectly inverted font colours. The lockscreen seems to be similar to the old one and not the webOS-esque circular lock in the Honeycomb UI for tablets. The browser has been redesigned in Honeycomb with no visible tabs.
Well, there is not much to learn from there, but the interesting part is that the emulator can be reverted to a smartphone UI layout with a lower resolution. This does show signs that Honeycomb could be run in dual modes. Although, there is something to look forward for Google to set themselves for the dual-UI strategy in the future.
